(a) Given that density is usually expressed in the units of g/cm3

Lena [83]

Answer:

0.690g/cm^3

Explanation:

•Mass: <em>2.331g</em>

•Volume: 3.375 cm^3

One side is 1.5cm.

1.5^3

•Density: Mass/Volume

Mass = 2.331g

Volume = 3.375cm^3

2.331g/3.375cm^3

0.690g/cm^3

<h2>Density: 0.690g/cm^3</h2>

A chemist prepares a solution of iron(II) bromide (FeBr2) by measuring out 46. g of iron(II) bromide into a 400. mL volumetric f

schepotkina [342]

Solution

Given mass of FeBr2 = 85.5 g

Molar mass of FeBr2 = 215.65

No. of Moles of FeBr2 = Given Mass / Molar mass = 85.5 / 215.65

No. of Moles = 0.3964

Given Volume is 450 mL i.e. 0.450 L

Now Concentration = 0.3964/0.450

Hence Concentration = 0.881 mol/L
